Quality of grass cover on the basis of starch value and new feedstuff evaluation system (on platform ME, NEL, NEV) was evaluated. Starch value of grass cover was 45-48 x 100 percent dry matter, ME 9.5 to 11.0 MJ kg** (-1). Fertilizer doses (120 kg N + 35 kg P + 70 kg K) per ha had no significant effect. Changes of metabolizable energy are significant during vegetation period. The ME value in young cover was 12.5 MJ kg** (-1), in older cover 8.1 MJ kg** (-1). Prediction of grass cover energy utilization in the Lolio-Cynosuretum typicum association was investigated for 3 years, and is supposedly higher in rearing young cattle and in fattening when reaching higher yields
